Sucks for those that can only AC charge at 32 amp max. Would have to hope it gets stuck at 16 amps.

For whom does it suck and why? While I will Supercharge when I take a road trip, the majority of my charging is via a NEMA 14-50 (topping out at 32A on my SR+) using my Mobile Connector at work. Considering it is free, it definitely doesn't suck.Sucks for those that can only AC charge at 32 amp max. Would have to hope it gets stuck at 16 amps.
I meant that the issue is being seen when charging at 32 amps when the vehicle is capable of 48 amps. SR and the MR cap at 32 so wondering if it would show up as 16 amps for those vehicles.For whom does it suck and why?

Warrenty on the part?I can report that, two days ago, the second 16A module in my PCS failed. I can now only charge at 16A. I'm going on a roadtrip next week to a location with a destination charger, and if the third module fails… I'll be SOL.

Warrenty on the part?
No I've been following along. If it's your third one was wondering if there was a warranty on the new part itself.You must be new to this topic. I am in dispute with Tesla over it, waiting for a decision from the arbitrator. This post might help.
No… see the link. The PCS contains 3 modules, each handling 16A of power. 16 x 3 = 48A total possible charge from an AC charging station. Those modules start to fail prematurely, one at a time. The first one died on me over 9 months ago. Now the second one has died. If the third goes… I won't be able to charge at either Level 1 or Level 2, period. Covering these components under the HV Battery and Drive Unit warranty is precisely what my dispute with Tesla is all about. None of the parts have been replaced yet, as I'm waiting for the arbitrator to render a decision.No I've been following along.

Seems like it may be a deeper issue of they've failed more than once.
OK. I remember that now. This is completely crazy this isn't covered.No… see the link.

have you updated your complaint stating that a second module has now failed? Tesla not covering this under the longer warranty is insane.No… see the link.

Since it says "16a/16a" it is likely that the problem is your wall connector, not the car. It's either configured wrong, or it is broken in some way.My tesla home charger is set at 32A which is the max value I can type in.
However, my M3LR only shows 16A max and I get an error with 3 multiple different AC/DC charging stations (2 home tesla wall chargers on different location and one non tesla charger in the city centre):
THE ERROR IS:
"(PCS a019) Power grid or vehicle issue limiting AC charging. Unplug and retry / Try different charging location."
The amps showing in the car reach 16A/16A (even though wall charger is set to 32A) and max power I can reach is 7kw, then the above error pops up.
Fast charging works ok, low power charging (3kw) directly from kitchen outlet also works without error.
I scheduled an appointment on 11/9 at Tesla service and I will see what they have to say.
But I am scared reading about part or battery replacements, my car is 1 year old and only has 5000miles on the clock.
Any idea what is going on? Am I doing something wrong?
the thing is that I tried on 3 different onesSince it says "16a/16a" it is likely that the problem is your wall connector, not the car. It's either configured wrong, or it is broken in some way.
Ah, yep, PCS (power conversion system) failure. There has been a rash of these. It's the onboard charger in the car that converts from the AC electricity coming in, into DC to go directly into the battery. And as you noticed, fast charging like Supercharging still works fine, because that's already converted outside of the car and is bypassing the PCS.

unfortunatell, yes PCS will be replaced, hopefully in the beginni g of next week.Ah, yep, PCS (power conversion system) failure. There has been a rash of these.

Power Conversion System (PCS) failure
There are a few threads going here and on other forums for charging issues that turn out to be PCS failures. Most owners notice the failure when they are AC charging (Wall Charger or Mobile Connector). The charge rate will drop from 48A to 32A or 32A to 16A and give an error message saying...teslamotorsclub.com
The retrofit will not have anything to do with the PCS.does anyone know when they start offering CCS retrofits, if that has anything to do with the PCS (replacing it)? I do want CCS compatibility added to my 2018 3, and if it may also fix the PCS issue if they need to replace it anyways, it would be a double win
